This chip uses 264-byte pages, not the 256-byte pages found in the AT45DB021E-SHN2B-T variant. If your firmware's SPI driver assumes 256-byte boundaries (common in generic SPI Flash libraries), you will need to adjust the page-write routine. The extra 8 bytes per page are available as a scratchpad or ECC area if the controller supports it.
No end-of-life notice on record, so it is safe to qualify for new production.
The AT45DB021E is the newer generation and is generally a drop-in replacement for the AT45DB021D in the same 8-SOIC package, but verify the page organization (264 bytes vs 256 bytes) and any minor timing differences in your specific application.
